We consider a branch of queueing theory, retrial queueing systems, which is characterized
by the following basic assumption: a customer who cannot receive service (due to finite …

In this work, we present a bibliography on retrial queues which updates the bibliography
published in this journal in Artalejo (1999)[7]. The bibliography is focused on the progress …

Vacation models deal with a very important class of real life congestion situations
encountered in day-to-day as well as in industrial scenario. A vacation in queueing context …

In most of the queueing models, service is considered to be complete without any
interruption. But in reality, queueing systems are subject to interruptions due to failure of …

Abstract Analysis of an unreliable-server retrial queue with customer's feedback and
impatience is presented. Truncated classical and constant retrial policies are taken into …

This paper studies a general retrial queue with balking and Bernoulli feedback, where the
server operates a modified vacation policy. If the server is busy or on vacation, an arriving …

A Markovian single server feedback retrial queue with linear retrial rate and collisions of
customers is studied. Using generating function technique, the joint distribution of the server …

We analyze an unreliable M/M/1 retrial queue with infinite-capacity orbit and normal queue.
Retrial customers do not rejoin the normal queue but repeatedly attempt to access the server …

This paper is dedicated to the study of a machining system with standby provisioning,
feedback and working vacation policy of the server. The failed machines are permitted by …

We consider an M/G/1 retrial queue with general retrial times where the blocked customers
either with probability q join the infinite waiting room (called priority queue) or with …
